It is pornographic, why watch it? When a man watches such such movies, he can feel sensual lust.
That is part of the evil lusts of the eyes. That is evil. It causes discontentment for you, for your wife, for your life partner. As though if there are no pornographic movies to watch, you do not like your wife anymore.
God hates that.
Let us read Malachi 2:15,
15. And did not he make one? Yet had he the residue of the spirit. And wherefore one? That he might seek a godly seed. Therefore take heed to your spirit, and let none deal treacherously against the wife of his youth.
Love the wife of your youth. Your wife who has been with you for the longest time, you should love her, do not deal treacherously with her. It is a form of treachery. If you need pornographic films, movies, and magazines, in between you and your wife.
That is infidelity, so avoid that.
Though sometimes it cannot be avoided, when you turn the TV on, unintentionally, there is such content. You will be surprised. But to willfully desire it to make it a habit to watch pornographic films, that is against the will of God because it encourages something bad.
That is an evil thing because aside from what the bible says, there is a study of psychiatrists about that.
Porn may also literally shrink the brain, a 2014 study in the journal JAMA Psychiatry found. Men who regularly consumed porn had smaller brain volume and fewer connections in the striatum, a brain region tied to reward processing, compared with those who didn't view porn.

The brains of those addicted to porn shrink. In the Bible, that is part of what God commands us, to avoid the evil lust of the eye.
No comment... hahaha... All I can say is sex is a part of love. love is different from lust. If you are in legal age watching adult movies is not bad, but if you are a kids its a big NO for me.
